In the past, we have had the privilege of providing assistance to prestigious institutions such as the Chancellery of the President and the Sejm. One of our partners played a key role as a member of the Ministry of Regional Development team conducting audits of projects under the Special Operational Program for Transport (SOPT) in 2006. Additionally, they have been actively involved in various other audits and inspections.

We generally operate from Monday to Friday from 10.00 a.m. to 5.00 p.m., however, in urgent cases, services will be provided in accordance with arrangements agreed upon between the client and K&K. Our services can be offered at either the K&K office or the client's premises, and we also facilitate communication through electronic channels and/or telephone consultations. At the client's request, consultations on specific matters can be scheduled at mutually agreed times.
